Subject: [PATCH] force entity dismount during teleportation
|
|
|
|
Entities must be dismounted before teleportation in order to avoid
|
|
multiple issues in the server with regards to teleportation, shamefully,
|
|
too many plugins rely on the events firing, which means that not firing
|
|
these events caues more issues than it solves;
|
|
|
|
In order to counteract this, Entity dismount/exit vehicle events have
|
|
been modified to supress cancellation (and has a method to allow plugins
|
|
to check if this has been set), noting that cancellation will be silently
|
|
surpressed given that plugins are not expecting this event to not be cancellable.
|
|
|
|
This is a far from ideal scenario, however: given the current state of this
|
|
event and other alternatives causing issues elsewhere, I believe that
|
|
this is going to be the best soultion all around.
|
|
|
|
Improvements/suggestions welcome!
